How would you solve the following trig equation sin(x)=-0.5 by isolating the x?
Vitek1552 [10]

Make use of the inverse sine function. Take the inverse sine of both sides of the equation. Of course, within the appropriate limits, the inverse sine of the sine function is the original argument, as is the case with any inverse function: f⁻¹(f(x)) = x.

... sin⁻¹(sin(x)) = sin⁻¹(-0.5)

... x = sin⁻¹(-0.5)

... x = -30°

_____

You need to be careful with inverses of trig functions, because they are only defined over a limited domain and range. The range of the inverse sine function is -90° to 90°, so, for example, sin⁻¹(sin(150°)) = sin⁻¹(0.5) = 30°.

What is the solution to the equation 2k-10/-7=8
Rasek [7]
\sf\dfrac{2k-10}{-7}=8

Multiply -7 to both sides:

\sf2k-10=-56 

Add 10 to both sides:

\sf2k=-46 

Divide 2 to both sides:

\sf~k=-23

Answer:

240 \leq 12.5p + 65

14 \leq\\ p

Step-by-step explanation:

I'll explain the equation in different parts

12.5p - Since the number of times he visits is unknown, it has to be a variable. With each visit, however, he earns 12.5 points.

65 - This is a set value that remains constant

240 \leq\\ - Since he needs AT LEAST 240 points, he needs 240 points or more to get his free ticket

As for solving the equation just use properties of equality

240 \leq 12.5p + 65

175 \leq 12.5p

14 \leq\\ p
